To @ZZ whom, it may concern,

Be it known that I, VALTER MGLAREN,

proved FApparatus for Manufacturing CupA4 Pastry, oi? which thefollovvingis a specilication.

My invention vrelates to the artiofA cup it pastry`manui`acture in whichit is the prac tice to mold'and bake thegarticles in male and femaleelement baking` molds,feither by use oit hand operated-devices, or bythe use oll automatic machinesi 'lli construction and .manipulation ofthe molds has been such that an excess of batter above the amountrequired 'to term a perfect cone, must usually-be present in Iorder thatall `cavities of the mold unit may make full -cenes, ,This practice' hasresulted in greatA Waste of materialyranging from 20 to 40 per centdependingupon the apparatus eniployed and the skillI olf' the operator.

lt is therefore one of the objects of my present invention to provide anapparatus of such construction that by the use of which this Waste maybe practically eliminated and perfect cones made Without their being re-Se quiredto be trimmed` thereby obtaining a greater number-ot perfectcones from a given quantity of flour than has heretofore been possiblewhen employing the methods and apparatus in vogue Aprior to my inven'ltion. l

A further object ofp my invention is to provide means whereby the battermay be Worked down and finally compressed Within a compartment ofuniform 'volume V(re- '40 gardless of thusual variations in the quantityot batter delivered to the mold cavity) thus enabling the production ofa product oi' exact dimensions or size With smooth edges and of' anydesired shape or design.

- ln carrying out my invention, I. preferably employ molds of the usualmale 'and female types (either solid bed, for making paste cones, orsplit molds, for making sugar cones) ypreerably providing the mold `witha throat and providinguthe` core with a neck, the latter being designed'to' lit the throat et the mouth ot the female part, before the 'core isforced home, thus elosing the cavity, upon vthe partial insertion' ofthe core, aga-inst the escape cflthe batter and on the final seating ofthe. core compress the lfn the art as heretofore practiced, 'the` yetallowing for the more or less 'tree escape of steam, and enabling' thecore to bayeciprocated",Y (raised and lowered) to u Work the battertollthe entire mold cavity and batter to itsv final' form andv size.

Another object of the present invention is to provide a moldv of suchconstruction that vadequate provision is made for the accurate centeringofthe core, .thus enabling a cone 55 to be produced Whose Wall will beof uniform thickness all around.

The inventionL also resides in those novel teaturesof construction,comb'mation` and arrangement of parts, all of which Will be first fullydescribed, then specifically pointv ed out in the appended claims andillustrated 'in the accompanying drawingsg in Which:-

Figure l is a vertical section of a baking mold unit of the typeemploying a split female mold element, the batter charge having beenintroduced and the core partly in sorted, the mouth ofthe mold beingclosed against the escape of batter.

'Figure 2 is a view similar to Figure l2 showing' the intermediateposition of the core in dotted lines and the final position in fulllines. f l 1 Figure 3 is a .detail viewlsimilar to Fig ures l. and 2, ota modification and showing the core in its inal position after the steamhas escaped and the batter has been compressed to the size and shapedesired.

Figure 4 is a vertical section of a solid bed mold in which the neck otthe coro is en larged and the throat of thernold is correvspondinglyenlarged so.y as to permit the ready removal of .the cone from the moldcavity, the core being shown in the intermediate position in4 full linesand in the final position in dotted lines.

'In my improved construction ot' mold the molding cavity is vbelow thetop' tace throat 5 islforrned in themold which conin located a suitabledistance `(3 of theimold and a inunicates withthe` molding" cavity andforms a shoulder 4 where the throat 5 meets the iippcr end ot themolding cavity. -7

This will mold cavity after it has been formed. n

In the form shown in Figure 5, over-hang ing portion 4 of the mold isproduced by the insert plug the female mold and is removable for thepurpose of ,allowing the withdrawal of the cone when it has beencompleted, the plug bored to form the throat 5, as

In Figure 4, the over-hanging part, which vforms the top edge surface ofthe cone, is

providedat 4tL by the enlarged neck of the core.

ln the practical application of the invention, the batter may be placedin the mold the batter introduced into the same and causes the batter tobe spread upx 'ardly in the mol'dcavity :is the neck 8 tits the throat 5with a werking" it, Vthe steam will escape between engaging surfaces ofthese parts tbut the batter cannot escape Molds of the split type areusually provided with a plurality movement or by The r`core T'is car-v'-into theI throat ,the steam action and 11 which forms a part olfA andhence is confined within the cavity of the moldt The core isthen'turtlrer projected into the cavity, either by continual asuccession oi reciprocating -or teetering movements zgraduallyapproaching the inal seating oi the, core. This results in the alternateincreasing and decreasing off cavitytofworlrthe batter into all oftherecesses of the cavity. yThe operation of reciprocating the core as itis being'seated is conducted such number'o times as may be Jouiiddesirable in practice until the escape` of steam has practicallysubsided, at which downward gradual the pressure within the mold timethe batter will then fill the molding cavity 'and become practicallyevenly dis' tributed at the mouth of the same, the shoulder 4 acting asa baille for the risingr batter and assisting in its distribution. Theinalmovement of the core to bringit to its fully seated position (seeFigure 3) results in'av nal compressionbf the mads', and theyelimination of .blowholes If the batter in swelling, vfills up one sideof the molding cavity more than at another place and works y ofthethroat into-the molding cavity on the final movement of thecore.A

l/Vhile the above described manner of manipulating the core is thepreferable one, it is obvious that other manipulations of the partsmaybe eii'ected to obtain the desired result` as,- for instance, insteadof recipro eating the core it may be forced to its .final seatedposition by a .preferably continuous gradual pressure, cally, or throughthe weight of the core bar and core, which may be made heavy enough toperform this function. 4

Should' the amount of batter fed into the moldv cavity -be /less thantheA exact amount requirech'the batter' will `be swelled, up by therecip ocajingr movements of the core until it fills the cavity.. ployed,thebatter will be compressed within the mold cavity. In the first place,a slightly lighter cone is produced than in the latter case, butin. bothinstances the final size auf vshape of the cone will be the same.

It wi l be noticed that oneof the essential Afeatures of my presenttypeoi mold resides in providing a mold in which the material worked upon isconfined, as it were, in a closed chamber, the area of which is thendecreased and pressure applied to compact the mass of the article into adefinitely defined size and shape. j l

When the core is 'seated with anni-directional continuous motion, thevents 10 may itwill-be 4forced down out either applied me'chanil If aslight excess of batter is emthe operation before the batter reachesthe'4 n shoulder 4 and thus elose the vents l07 therelli seated somewhatmore rapidly than would case.

The drawings illustrate preferred embodiments of my invention but do notWish to be understood as being limited to the spe citic embodiment shownand described as changes in the details of construction may be made tosuit the particular machine or apparatus in. which the invention is tobe embodied.

ln' this application, l make no claim to the method of operation ormethod ot male ing the cones b the use ot' the apparatus herein describeas that forms the subject matter ot my application tiled October t5,1919, Serial No. 328,655, oit which. application the present applicationis a continuar tion in part. y
